Iterative Poisson Solvers for Self-gravity with the GPU Code Astaroth
Ruben Krasnopolsky, Touko Puro, Wei-Wen Li +5
We present the development and benchmarking of Poisson solvers for graphics processing units (GPUs). Implemented in the Astaroth platform, the solvers feature high computational ef…
Constraining Active Galactic Nucleus Jets with Spectrum and Core Shift: The Case of M87
Kouichi Hirotani, Hsien Shang, Ruben Krasnopolsky +3
We analytically model stationary and axisymmetric active galactic nucleus jets, assuming energy conservation along each magnetic flux tube. Using very-long-baseline interferometry…
Polytropic Wind-Driven Bubbles and their Shock Structures in Radially Stratified Ambient Media
Dmitrii Zagorulia, Hsien Shang, Ruben Krasnopolsky
We extend the analytic expressions for polytropic wind-driven bubbles and their shock structures, formulated initially in Koo and McKee 1992(a,b), focusing on spherically symmetric…
Resistive Collapse of 2D Non-rotating Magnetized Isothermal Toroids: Formation of Pseudodisks
Ya-Chi Wang, Hsien Shang, Ruben Krasnopolsky
The collapse of singular magnetized toroids (Li & Shu 1996) is a natural representation of an early phase in star formation, bridging the prestellar and protostellar phases of the…
R-JET: A postprocessing code for radiative transport in relativistic jets
Kouichi Hirotani, Hsien Shang, Ruben Krasnopolsky +1
We describe a post-processing radiative transport code for computing the spectra, the coreshift, and the surface-brightness distribution of special relativistic jets with arbitrary…
How Does a Protostar Form by Magnetized Gravitational Collapse?
Indrani Das, Hsien Shang, Ruben Krasnopolsky
Star formation through the dynamical magnetized collapse remains an active area of astrophysical research. We carry out a comprehensive exploration on the magnetized gravitational…
